TRACTION-LUG.

, 'Applicationfiled May 19, 1920. "Serial No. 382,662.

To all whom it may concern:

the rim of the wheel, the inner portions beling provided with recesses to receive the spokes of the wheel, and b'elng further provided with extending arms adapted to be' positioned on the inside of the telly of the wheel, the arms being provided with open ings for the reception of bolts, slotted connecting plates connecting the arms of one pair of lugs'to the arms ofthe next adjacent pair, bolts or other fastening means arranged in said slots and in the'openings in said arms, the lugs being provided with radial'slots on each side, a yoke of strap adapted to be re ceived in said slots, and a supporting rod secured to each of said yokes and adapted to maintain said attachment in position.

It is an object oi the present invention to produce a device of this character which may be readily applied to various types and sizes of wheels and which may be removed and replaced in very little time, and by the operator of the machine, or one not necessarily skilled in mechanics.

The invention comprises a pair ofcomplementary members which carry the traction lugs and are arranged on each side of the spoke, and means for securing the traction lug arranged near one spoke to the traction lug arranged around the next spoke, including a slotted connecting plate which permits adjustment of the attachment on wheels or" different'sizes. 1

In the accompanying drawings, we have shown one embodiment of the invention. In this showing,

Figure 1 is a partial side elevation of a vehicle wheel showing the invention applied.

Fig. 2 is a perspective view of the traction lug removed from the wheel. 7

Fig. 3 is a vertical transverse sectionalview of a wheel rim and tire Fig. 4: is'a detail perspective view of -the slotted connecting plate. -1

Fig. 5 is a detail view of a supporting means for the reinforcingrods, and

-F1g. 6 is a detail perspective view of the yoke or strap.

Referring to the drawings, the reference numeral 1 designates a'vehicle wheel havmg a :rim 2 and tire 3. The traction lugs are adapted to extend outwardly beyond the rim, as is the usual construction,*whereby they are brought in contact with the ground when the wheel enters a rut or is running-in ioktt ground, or in snowy'weather, and the le. "i

As shown, the lugs 4 are provided with complementary recesses 5 adapted to receive the spoke 6 of thewheel. Each of the lugs tending arms 7 having openings 8' forthe reception offastening. means: As shown in Fig. 1 of the drawings, these arms '7 are adapted to lie within the i11ner rimorwheel felly and substantially conform to the outline of the felly. A plurality of these lugs Specification of Letters Patent: Patented Feb 1921; v

--is provided with a .-pair of oppositelysexfastening means 12 may be passed through the slots and through the openings in the arms to secure the two members in proper position. It is readily apparent that the I provision of elongated slots will permit ad justment of the attachment to wheels of Va rious sizes. v

. Means are also provided for retaining the lug or attachment in proper position adjacentthe rim of the wheel. As shown, each of the lugs is provided with a pair of vertical slots or grooves 12. A connecting member consisting of a strap or yoke 13 having downwardly projecting arms 14 is provided, the arms 14: being adapted to enter the grooves 12'. A rod 15 is connected to each of these yokes or straps, the rods extending substantially arallel to the spoke otthe wheel. This member may be secured to the yoke by any suitable means, and as" shown, the end of the rod is threaded and is adapted to receive nuts .16 and 17 arranged above and below the yoke. The upper end of the rod is offset as at 18 (see Fig. 6) and is adapted to enter registering openings 19, arranged near the ends of plates 20 and 21. These two plates are bent or curved as at 22, and are adapted to be arranged around the spoke. ranged upon the threaded end of the rod 15, whereby the entire construction herein described produces a very eiiicient attachment for'automobiles and thelike for the purpose of preventing tie-ups, due to muddy roads. The device is also very effective as a. traction lug during snow storms and enables the user of an ordinary motor vehicle to travel through heavy snows without the usual difiiculties experienced in driving. The lugs arranged at right angles to the direction of travel give a very positive grip on the snow or other materialon the road, and the vehicle is propelled forward without difiiculty.

Itis to be understood that while we have described the preferred embodiment of our invention, various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention as defined by the scopeof the subjoined claims. c

Having thus described our invention, what we claim is:

1. A traction lug for vehicle wheels, comprising a pair of complementary sections 7 having a spokereceiving recess, arms carried by said sections and extending in oppo- A'nut 23 may be arto and extending substantiall site directions, and slotted connecting plates adapted to receive the arms of adjacent lugs.

prising a pair oi complementary sections having a spoke receiving recess, each section being provided with a pair of grooves, a. connecting member arranged in said grooves, and a supporting rod secured therethe spoke, and means for securlng said parts in position.

4. A traction lug for vehicle wheels, comprising a pair of complementary sections having a spoke receiving recess, each section being provided with a pair of grooves, a yoke having arms entering said grooves, and a supporting rod secured thereto and extending substantially parallel to the spoke,

and means for securing said parts in position.

In testimony whereof-We atfix'our signatures in presence of two Witnesses.
